ChangedState
CloneState

clone_state_with_topo_id	Clones the state of type T keyed to the given TopoId
do_once	call the provided function once and once only returns a unmmunt which will allow the do_once to repeat if .execute_if_activated() is called on the unmount. Example
execute_and_remove_unmounts
new_state
on_unmount
purge_and_reset_unseen_ids	Rudamentary Garbage Collection purges all unseen ids' state then resets the suneen ids list.
reset_unseen_id_list	Rudamentary Garbage Collection
set_state_with_topo_id	Sets the state of type T keyed to the given TopoId
state_exists_for_topo_id
unseen_ids
update_state_with_topo_id	Provides mutable access to the stored state type T.
use_state	Constructs a T accessor. T is stored keyed to the current topological context. The accessor always references this context therefore can you can set/update/ or get this T from anywhere.
use_state_current	Uses the current topological id to create a new state accessor
